Description

DIAGNOSIS A very small, yellow member of the flavens group whose major is marked by its strongly curved propodeal spine (as though the tip had “melted” backward); long scapes, which reach the occipital corners; all of the sculpturing on the anterior half of the head consisting of longitudinal carinulae, with the posterior half smooth and shiny; and pronotal humerus in dorsal-oblique view rounded. Similar to onyx, but in the major, citrina has a more curved propodeal spine, far less carinulation on the dorsal head surface, and longer scapes, among other differences.

See also the less similar Pheidole grex and Pheidole humida.

MEASUREMENTS (mm) Holotype major: HW 0.66, HL 0.70, SL 0.54, EL 0.06, PW 0.38. Paratype minor: HW 0.46, HL 0.50, SL 0.54, EL 0.10, PW 0.28.

COLOR Major and minor: concolorous yellow.
